IRVING L. STONE, OF BATTLE GREEK, MICHIGAN.

OPERA-CHAIR.

SPECIFICATION forming part of Letters Patent No, 325,283. datedSeptember 1, 1885.

Application filed May 31, 1884.

To all whom it may concern:

Be it known that I, IRVING L. STONE, of Battle Creek, county of Calhoun,State of Michigan, have invented certain new and useful Improvements inOpera-Chairs, of which the following is a full and exact description,reference being had to the accompanying drawings, making part of thisspecification.

My invention consists, first, in the combination, with the standards andseat connected together by the front supporting-braces, of a rear braceconnected at its forward ends to the sides of the seat and having'asingle central connection with the frame of the standards.

It further consists in the combination, with the standards and seatconnected together by means of the forward supporting-braces, and withthe hinged or pivoted back, of arms or links connected to the seat andto the lower portion of the back, whereby said links may form a supportfor the seat when ext-ended.

It further consists in the combination, with the standards having theswinging-back pivoted therein, of the pivoted folding-seat connected tothe swinging-back by means of the arms or links, whereby the lower edgeof the back is caused to move toward the rear edge of the seat when thesame is lowered into its horizontal position or moved into an upright orperpendicular position as the seat is folded.

It further consists in the combination, with the standards and seatconnected together by means of the forward side braces and thecentrally-pivoted brace, of arms or links connecting said seat andback,whcreby the seat is allowed a free rearward and upward movement anda firm support provided for the seat when extended.

It further consists in the combination, with the pivoted back providedat its lower swinging end with the projecting arms for engaging thebuffers arranged in the standards, of the pivoted seat connected to theback by means g of the arms or links,whereby the rear edge of the seatis caused to rise as the pressure of the occupant is removed therefrom.

It further consists in the combination, with the back and seat connectedtogether by means of the arms or links, of the buffers connected to theseat to engage said arms or links when (No model.)

the seat is extended, all as and for the purpose hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of myimproved operachair, a portion of the seat being broken away to show themanner of connecting the links and braces to the seat and back. Fig. 2is a sectional view of the same, showing the seat extended for use, andFig. 3 is a similar view showing the same folded.

The standards A may be made in any usual or preferred form, and areprovided at their lower ends with projecting lugs or feet through whichto attach the same to the base or floor, and at their upper ends aremade in bracketform to receive and support the arms B.

The back 0 consists, preferably, of an outer frame-work made in anydesired form or configuration to combine lightness and strength, thecentral portion being filled in with wood or other suitable material.This back upon each side, about centrally of its height, is providedwith a lug or arm, B, which projects therefrom at right angles to theface of the main portion, and through which the back is connected to thestandards, a pin or bolt, Z), passing through a perforation formed inthe lug or arm and engaging asimilar perforation formed in the standard,and said pin or bolt forming a pivot on which the back may swing. Thelower end of this back is further pro vided upon each side with aprojecting arm, I), which plays within a recess, A, formed in thestandard, and by its engagement with the front and rear wall thereoflimits the swing ing movement of the back.

The seat portion consists of an out-er rim or band, D, having a rib, d,formed on its inner face, and upon which rib the central portion of theseat rests, said central portion being made of board or of any othersuitable material corresponding to the covering or central portion ofthe back. The rim D, upon each side near its forward edge, is providedwith a downwardly-projecting ear, d, through which the supporting andholding arms are connected to the seat portion.

An arm, E, is connected to each of the standards near their lower endsby means of a pivotpin, 0, and extending up therefrom is connected tothe forward end of the ear (1, as shown, said arms forming the supportfor the forward edge of the seat.

A brace, F, made in V form, is secured at its central portion by meansof an eyebolt or staple to a board or bar, G, extending between the twostandards, as shown, and has its forward projecting ends connected tothe rear ends of the ears (1, as hereinafter described.

To the lower edge of the back and upon each side are connected links orarms H, which eX- tend forward therefrom, and are connected at theirforward ends to the forward ends of the brace F, the ends ofsaidbracepassing through perforations formed in the forward ends of thelinks before being engaged with the ears d, the ends of said brace beingconnected to the cars by passing through perforations formed therein,and being secured in place by means of a washer riveted thereon, saidlinks H forming the connection between the seat and back. In the recessA, in each of the standards adjacent to the forward wall thereof, ismounted a rubber buffer, a, with which the projecting arms I) on theback engage when the seat is extended, the links H, which act to drawsaid back forward as the seat is extended for use, being of such lengthas to bring the arms 1) into engagement with the buffers before the seatreaches the horizontal position, and to compress said buffer as the seatis brought into said horizontal position by the weight of the user insuch manner that when the weight is removed from the seat the expansionof the buffer will cause the lower end of the back to be thrownbackward, and acting upon the seat through the links H to throw the rearedge of the seat upward. The lower face of the seat is also providedwith rubber buffers I, arranged thereon in such position as to engagethe upper face of the links H near their inner ends when the seat ispressed into its horizontal position, and forming a yielding support forthe seat upon said braces.

The board or bar G,to which the brace F is connected,is secured to thestandards through ribs K, formed thereon. This board or bar may have anydesired form of ornamental outline, and may be provided on its rear facewith a pocket or clips to hold a hat or other article. This support forthe arm can, however, if desired, consist of a straight iron rodextending across from one standard to the other, as shall be found mostconvenient.

By having the rear edge of the seat entirely disconnected from thestandards it will beseen that the seat is adapted to be folded from itsrear edge or upward and away from the occupant as he rises from theseat. It will also be seen that by connecting the links to the loweredge of the back and to the forward edge of the seat a firm support isprovided for the rear edge of said seat, and the usual frail pins forconnecting the seat with the standards are dispensed with.

Having now described my invention, I Claim 1. The combination of thestandards, the front supporting-braces pivoted to the standards, a seatpivoted to the front supportingbraces, and a second supporting-bracehaving a pivotal connection at its forward ends with the seat, and afixed single central pivotal connection with a bar or frame connectingthe standards, substantially as described.

2. The combination of the standards having the back pivoted thereto, theseat, arms or links connecting the'lower portion of the back to theseat, said links at some portion of their length being nearer togetherthan the width of the seat to support the rear portion thereof, andbraces connecting the seat with the standards, substantially asdescribed.

8. The combination of the standards having the back pivoted thereto, theseat, arms or links connected to the lower portion of the back and tothe forward portion of the seat for tilting the back when the seat isfolded, said links being pivoted at one end nearer together than thewidth of the seat, with arms or links connecting the seat with thestandards, substantially as and for the purpose set forth.

4. The combination of the standards, the seat, the forward side bracesconnecting the seat and standards, the second supportingbrace having acentral pivotal connection with a bar or frame supported between thestand- V ards, the back pivoted to the standards, and the linksconnecting the seat with the back, substantially as described.

5. The combination of the standards, the back pivoted in said standardsand provided at its lower swinging end with projecting arms, the buffersmounted on the standards in the line of movement of the projections onthe back, the links connecting the back and seat, and the bracesconnecting the seat and stand ards, substantially as described.

6. The combination of the standards having the back pivoted thereto, thesea arms or links connecting the seat and back, said links at someportion of their length being nearer together than the width of theseat, buffers connected to the seat to engage the links when the seat isextended, and braces connecting the seat with the standards,substantially as described.
